SPINNING-MACHINE, 80C.

SPECIFICATION forming part of Letters Patent No. 243,525, dated June 28,1881.

Application filed October 18, 1880. (No model.) Patented in GreatBritain January 26, 1880` T all whom it may concern.:

Be it known that we, EDWARD DENBY, J osEPH HELLIWELL, WILLIAM HILLARY,and IVILsON RILEY, kall of Keighley, in the county of York, GreatBritain, and subjects ofthe Queen of Great Britain and Ireland, haveinvented certain Improvements in Spinning-Machines, Ste., (for which wehave obtained a patent in Great Britain, No. 341, January 26,

ro 1880,) of which the following is a specification.

Theobject of our invention is to arrange the spindles in spinning,twisting, roving, and similar machines used in the manipulation offibrous materials in such a manner that the bobbins, when full of yarnor roving, can be what is technically termed dot'ed'7 by mechanicalmeans without having to disconnect `the fliers, and to regulate the dragupon the ber that the tension on the same, in its travel 2o from thefront rollers to the spindles, can be adjusted to suit the varyingcircumstances and nature of the fiber that is being manipulated. Snellbeing the object of this invention, we will describe the particularsthereof, aided by the accompanying drawings, in which- Figure lrepresents the front elevation of such portions of a spinning-framefitted with our improvements as are required to make clear ourinvention. Fig. 2 is a transverse sec- 3o tional elevation of the same.Fig. 3 is an enlarged view ot' one set or circle of spindles andV tubes,one of which is shown in section; 'and Fig. 4 is a cross-section throughthe flier-rail and center of whirl, showing the manner in which wesuspend the whirls and iers.

The lifter-rods A are connected to the ordinary lifters in the usualmanner. In the British patent No. 1,504 of 1853, for instance, isillustrated an arrangement of devices which 4o may be employed foroperating the lifter-rods.

At the top of rods A we form journals, in which are mounted one or moreshafts, B, secured together by any ordinary method. On these shafts areattached bosses C, the number '45 varying according to the pitch of iersand length of frame. To each ot' the bosses C are secured a number ot'fixed spindles, C', radi-- ating from the center of shafts B, eachspindle being covered by a tube, D, that is freeto re- 5o volve thereonandkept in position on the spindle by cap D', which is screwed ontoprojections on boss G. The tubes D and cups D' are more fully describedhereinafter. l

In place of the ordinary wire board we substitute bar E that extends thelength of ma chine. The fliers F are carried by tubes G, that passthrough the center of each flier-head and whirl H. These tubesGare eachsecured to and carried by a flan ge, g, havin g a bearing in a metalplate secured to the rail, as illus- 6o trated in Fig. 4. The whirls arerevolved by ordinary bands in connection with cylinder Oz, and the topof each whirl is recessed at H', for the purpose of lubricating tube G,to which communication is made by small holes from bottom of recess H'.This recess is partly covered by a thin plate which retains the oil, preventing the same being thrown off by the centrifugal force of therevolving whirl. The tiange G' at bottoni of tube Gis recessed also. 7oThe liber,after passin gbetween the frontrollers, is conducted throughhole'in the center of tube G to the revolving fliers F and spurl ontothe bobbins on vertical tubes D; 'Vhen the hobbin's are full of yarnready to be dotted the 75 frame isstopped and lit'terlowered such adistance that the tops of vertical tubes D are clear ofthe bottoms ot'iiiers F. The shafts B are then turned in thejournals until the nextseries of spindles on which the empty bobbins 8o have been placed arebrought in a perpendicular position and secured by placing catch J inthe top notch or indentation formed in the periphery of disk K, which issecured on shaft B. The lifter is then reversed,.the shafts B andattachments raised, and byturning cylinder O2 part of a revolution theyarn from the full bobbins is wrapped round the empty bobbins, now in avertical position. The threads of yarn between the full and emptybobbins are 9o then cut by means of a series of shears, de tails ofwhich are shown in Figs. 5 and 6, which are actuated in the followingmanner:

The bar L is carried by suitable brackets, and extends the length of theframe. To this 9 5 bar are attached, opposite to each circle of spindlesand tubes D, a pair of shear-blades, M and M', each blade beingconnected to a small bracket, N, the blade M to the top portion and M'to the bottom portion. These roo ing the blades of shears together andseveringL the threads of yarn. Vhen the lever O is released the spring Sat end of rod O draws the same into its original position, opening theblades ready for cutting the yarn at the next dofng; but this cuttingattachment forms no part of our invention. rIhe machine is then ready tobe put in motion, and when the bobbins are full of yarn another seriesofempty bobbins are brought to the top and the operation repeated.Therst-mentionedfull bobbins will have arrived at such an angle (shownin Figs. 2 at V) that they will slide ott' the tubes and fall onto anendless revolving cloth, R, which cloth will convey and deliver theminto a suitable receiver.

In order to keep the tubes D in position on the xed spindles, and at thesame time regulate the drag, we form at the bottom of each tube aiiange, l?, true with the axis ofthe tube. Over this ange we place acap, D', which screws onto a projection of boss C and is held inposition by spring P attached to the boss, and pressing against theroughened under side of cap D', so as to prevent the accidentalunscrewing of the said cap. Between the top surface ot' iange P and theunder side of cap D we place a flexible washer, Q., which forms acushion between the same. By screwingand adjusting the pressure of thecap D', compressing the flexible washer Q on flange P, the powerrequired to revolve tube D on tixedspindle C will bein proportion to thepressure of cap D on the said flexible washer, a-nd the drag upon thefibrous material will beincreased or diminished in proportion to thepressure that is put upon the said washer bythe capsD.

Our improvements are also applicable to machines for twisting yarns, andthe modas 019errmd for carrying out our invention is the same as thatalready described for spinning.

When applying our improvements to rovingi'rames we construct thespindles, tubes, and caps in the same manner as those described, butinstead of having a revolving shaft we mount a shaft at the top oflifter-spindles with only one set of spindles, which are in a verticalposition when the machine is in motion.

Fig. 7 is anend view of shaft and spindle tube in a vertical position.The shaft is held by a catch litting into notch in disk K. By raisingthe catch the spindles can be turned toward the operator, in theposition shown by dotted lines, and doifed in the usual manner.

Fig. Sis a detail of disk K that is secured on shaft B and used for thepurpose of keeping the spindles in spinning-machines in a verticalposition.

What we claim as our invention is l. The combination of the frame andthe flier ot' a spinning and twisting machine with a rotary shaft havingbosses C with fixed spindies C', and incasing-tubes D, adapted to turnon said spindles under the pull on the yarn, all substantially as setforth.

2. The combination of the frame and flier of a spinning and twistingmachine with a rotary shaft carrying fixed spindles C', incasingtubes D,and retarding devices for acting on said tubes, substantially asdescribed.

l 3. The combination of boss C, xed spindle C, and incasing-tube D, withscrew-cap D and yielding washer Q, as and for the purpose set forth.

In testimony whereof we have signed our naines to this specication inthe presence ot' two subscribing witnesses.
